Summary & Overview
HCPCS G9767: Evaluation for Endovascular Stroke Treatment in Hospitalized Patients
HCPCS Level II code G9767 denotes hospitalized patients with newly diagnosed cerebrovascular accident (CVA) who are being considered for endovascular stroke treatment. The code captures the set of assessments and decision-making processes used to determine eligibility for mechanical thrombectomy or other endovascular interventions in the acute care hospital setting. Nationally, tracking use of this code is important for measuring access to time-sensitive stroke therapies, hospital stroke care workflows, and adherence to emergent stroke care pathways.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical context, the typical inpatient service setting, and which stakeholders commonly process claims for these evaluations.
This publication provides benchmarks and operational context relevant to billing and coding for acute stroke evaluations considered for endovascular therapy, summarizes policy considerations that affect coverage and documentation, and clarifies what information is typically required on the hospital service line. Data not available in the input are noted where applicable. The intent is to inform billing, clinical operations, and payer contracting discussions at a national level without issuing clinical recommendations.
Billing Code Overview
HCPCS Level II code G9767 represents hospitalized patients with newly diagnosed CVA (cerebrovascular accident) considered for endovascular stroke treatment. This code captures evaluation and care processes focused on identifying candidates for endovascular intervention for acute ischemic stroke.
Service type: Evaluation for endovascular stroke treatment
Typical site of service: Inpatient hospital setting
Data not available in the input for associated taxonomies, ICD-10 diagnoses, and related codes.
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult admitted to a hospital with acute neurologic deficits suggestive of ischemic stroke (sudden hemiparesis, aphasia, or visual field loss). On arrival to the emergency department or inpatient unit, the patient undergoes rapid stroke assessment, NIH Stroke Scale scoring, emergent noncontrast head CT to exclude hemorrhage, and CT angiography (or MR angiography) to evaluate for a proximal large vessel occlusion. If imaging confirms an occlusion amenable to endovascular therapy and the patient meets time-window and clinical selection criteria, the interventional neuroradiology or endovascular neurosurgery team is consulted. The workflow includes obtaining informed consent, pre-procedure labs and coagulation status, anesthesia evaluation (conscious sedation or general anesthesia), and transport to the angiography suite for mechanical thrombectomy and/or intra-arterial therapy. Post-procedure care involves neurologic monitoring in a stroke unit or neuro-ICU, repeat imaging as indicated, secondary prevention planning, and discharge planning.
Commonly involved clinicians include emergency medicine physicians, neurologists (stroke specialists), interventional neuroradiologists/endovascular neurosurgeons, neuroanesthesiologists, critical care nurses, and radiology technologists. Typical site of service is the inpatient hospital or hospital-based angiography/interventional suite. The service type is acute inpatient endovascular stroke evaluation and treatment consideration for newly diagnosed cerebrovascular accident (CVA).
